.50 cal TC Maxi Ball Lead Bullet

The Lee #90396 bullet is a .517-inch, pure lead bullet weighing around 320 grains, designed for modern inlines and hybrid sidelocks with a 1:48 twist rate.

• The description claims that the bullet stabilizes well in a 1:48 twist but not in a 1:66 twist.
• The description claims that under 100 yards, there is little benefit to the bullet's slightly flatter trajectory compared to a 250 grain sabot slug.
